The Shadow Systems Elite Trigger Assembly (brand part number SGK-1003) brings a premium flat-faced trigger feel to a drop-in kit built for daily carry and heavy-duty use on Gen 3 and Gen 4 Glock pistols in 9mm, .40, and .357 Sig. Shadow Systems keeps the trigger safety fully intact and drop-tests every design well beyond the standard 3.3-foot muzzle-down test, running drops from as high as 22 feet. The flat-faced profile gives most shooters a crisper, more controlled break and makes it easier to shoot to reset, while a shorter, cleaner reset point improves speed without compromising safety for daily carry use. Shadow Systems torques and Loctites every set screw before it ships, and its triggers hold up: with thousands in the field and units tested past 15,000 rounds, only two have ever come back with an issue.
